Stratimikos: add build workflow to support automated generation of ParameterLists.

Developer requirements:
* copy stratimikos/doc/parameterList directory to <pkg>/doc directory
* modify createValidParameterList.cpp
* copy stratimikos/build_docs files to <pkg>/doc directory
* add <iframe src="pkg.xml"...></iframe> to .hpp file where ParameterList will be displayed

Build and make normally. In build/packages/<pkg>/doc/parameterList, run ctest
to create the pkg.xml. In build/packages/<pkg>/doc directory, run build_docs.
You can see your documentation in build/html/<pkg>.
Add unit-tests for ghosting shared entities.

First test demonstrates that a ghosting can't contain nodes that are

Second test demonstrates that a ghosting can contain shared nodes from
the owning proc as long as they are not already shared on the destination.
